Trust Local Solution

UserNeeds changes for IntuneL_TrustCenterSolution

Supported on SUPPORTED_Windows7 (defined in the Windows templates)

5568.1000

What it does

Suppresses prompt that asks to load a locally installed full-trust solution of a Document Information Panel in the background. This is normally shown if a full-trust solution is deployed and there are bound properties in the document (e.g. lookups) that must load the Document Information Panel in the background to retrieve the contents of the property. Enter pairs corresponding to the Document Information Panel solution path and a value of 1 to disable. If the value is set, the user will not be prompted when loading the full-trust solution in the background. The solution will load normally (and any non-related warnings that exist).

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: L_empty421
